The scaling of metabolic rate with body mass has long been a controversial topic. Some
workers have claimed that the slope of log‐log metabolic scaling relationships typically …

Economic models predominate in life history research, which investigates the allocation of
an organism's resources to growth, reproduction, and maintenance. These approaches …

Reproduction includes two energy investments—the energy in the offspring and the energy
expended to make them. The former is well understood, whereas the latter is unquantified …

A landmark, radically uplifting account of our species' progress, from one of the world's
preeminent thinkers.“Unparalleled in its scope and ambition… All readers will learn …

The classic anthropological hypothesis known as the “obstetrical dilemma” is a well-known
explanation for human altriciality, a condition that has significant implications for human …

Human activity is changing climatic conditions at an unprecedented rate. The impact of
these changes may be especially acute on ectotherms since they have limited capacities to …

Drawing on recent advances in evolutionary biology, prominent scholars return to the
question posed in a pathbreaking book: how evolution itself evolved. In 1995, John Maynard …

DNA sequences evolve at different rates in different species. This rate variation has been
most closely examined in mammals, revealing a large number of characteristics that can …

Early survival is highly variable and strongly influences observed population growth rates in
most vertebrate populations. One of the major potential drivers of survival variation among …

The life histories of animals reflect the allocation of metabolic energy to traits that determine
fitness and the pace of living. Here, we extend metabolic theories to address how …
